摘要
目的探讨大鼠腹壁浅动脉穿支皮瓣的解剖学特点,为该皮瓣切取提供解剖学依据。方法 SD大鼠27只,7只行大体解剖,描述该皮瓣的解剖学特点;20只经颈总动脉行明胶-氧化铅灌注,并通过图片处理技术测量相关数据。结果腹壁浅动脉由股动脉发出后在穿浅筋膜处发出第1个分支,随即分为内外侧支,分别与胸外侧动脉和胸背动脉吻合。其外径在股动脉发出处为(0.46±0.02)mm,在穿经浅筋膜处为(0.46±0.02)mm,其营养面积为(18.37±3.67)cm2,其与胸背动脉的吻合区距离腋下水平线和腹中线分别为(5.34±0.86)cm和(4.38±0.38)cm;与胸外侧动脉的吻合区距离腋下水平线和腹中线分别为(6.28±0.69)cm和(2.04±0.33)cm。结论大鼠腹壁浅动脉解剖位置和外径恒定,是游离皮瓣移植、皮瓣动脉增压、血流动力学研究等的理想模型。
Objective To investigate the anatomy of the superficial epigastric artery perforator flap , and to provide anatomical basis for harvesting flap .Methods Of 27 SD rats, 7 were used for gross anatomy observation and anatomic characteristics and 20 rats for lead oxide-gelatin injection followed by computer picture processing , measurements and the related parameters recording .Results The superficial epigastric artery originated from femoral artery , and gave off its first branch when passed through the superficial fascia .The trunk branched into a lateral perforator and a medial perforator , which anastomosed with thoracodorsal artery and lateral thoracic artery , respectively .The average external diameter of superficial epigastric artery was （0.46 ±0.02）mm at its starting point,and（0.46 ±0.02）mm at the superficial fascia level . The nutritive area of superficial epigastric artery was （18.37 ±3.67） cm2 .The anastomosed area with thoracodorsal artery and lateral thoracic artery was（5.34 ±0.86）cm and（6.28 ±0.29）cm, respectively, away from the horizontal line through axillary,and （4.38 ±0.38）cm and（2.04 ±0.33）cm, respectively, away from the ventral median line.Conclusion The position and external diameter of superficial epigastric artery are constant , and the superficial epigastric artery perforator flap is a ideal flap model for research on free flap transplantation , flap supercharging , and hemodynamics .
